"AT89C51单片机烘炉温度自动检测系统硬件设计及实现"

The hardware design of the automatic temperature detection system for kilns is the focus of this graduation project. The system is based on the AT89C51 microcontroller and is capable of detecting and storing the surface temperature of workpieces and the oven temperature in four channels. It also includes functions such as sensor failure alarm and low battery alarm. The use of a new type of ferroelectric memory instead of traditional SDRAM ensures the reliability of data storage in the system. The temperature detection instrument can be placed in the heat insulation device during operation, making it very convenient and practical for the instrument to move along the production line with the workpiece. The main technologies used in the system include data acquisition and processing, computer detection, and FranklinC51 programming. The developed kiln temperature automatic detection system is a hardware development based on microcontroller-based computer detection technology. Key words: microcontroller, kiln, temperature detection, serial communication.
